The PCV valve or Positive Crankcase Ventilation valve is an important part in the FSI engine, which is prone to failure.  When this part fails you may experience a variety of issues.  The vehicle may have a loud whistle noise coming from under the hood, or possibly running rough due to a large vacuum leak. This may even lead to a loss of power coming from a bad check valve in the PCV, causing boost from the turbo to leak past the PCV.  If you take a look at the video we have linked below there is a clip with a 2.0t FSI engine running with a bad PCV valve.  Please note that while that one is obnoxiously loud and obvious yours may not fail like this.  If you are trying to track down a vacuum or boost leak that you cant find, a new PCV valve is a great option.

 

There are 2.... How do I know which one I need?

This part has been updated many times and it is imperative you get the most updated correct part for your car.  To further complicate this VW and Audi has a couple of different PCV valves on this engine which were not interchangeable.  If you put the wrong PCV valve on your FSI it will likely run very poor or not at all.  To determine which PCV valve you need it is best to get the original part number from the one in your vehicle.  This will allow us to get you the correct and most current version of this part.  The part number can be found on the bottom of the PCV valve shown in the picture above.
